LOCKING DEVIGE.

SPECIFICATION forming part of Letters Patent No. 775,957, dated November29, 1904. Application filed May 2, 1904. Serial No. 205,870. (No model)Be it known that I, CLARENCE AcToN W 1L- soN, residing at Hoboken, inthe county of Hudson and State of New Jersey, have invent ed certain newand useful Improvements in Locking Devices, of which the following is afull, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to locking devices.

One of the objects thereof is to provide a simple and efcient form ofspring-lock.

Another object is to provide a device of the above type which is adaptedto be secured to or made integral with a pivoted member in the nature ofa hasp.

The invention accordingly consists in the features of construction,combinations of elements, and arrangement of parts, which will behereinafter described, and the scope of the application of which will beindicated in the following claims.

In the accompanying drawings, which illustrate two of the variouspossible embodiments of my invention, Figure 1 is an elevation of a lockembodying my invention attached to a hasp. Fig. 2 is a similar Viewshowing a slightly-different form of lock and hasp. Fig. 3 is a plan ofthe same, showing associated parts. Fig. 4 is an elevation of the lockshown in Fig. 2, the upper portion of the casing being removed in orderto show the mechanism thereof. Fig. 5 is a cross-section of the same,taken on the line ai .fr of Fig. 4. Fig. 6 is a View similar to Fig. 4of a slightly-diiferent embodiment. Fig. 7 is a crossseetion on the linefz/ g/ of Fig. 6. Fig. 8 is a cross-section on the line s of Fig. 6.

Similar reference characters refer to similar parts throughout theseveral views.

Referring now to Fig. 3, A represents a door or window, and B a frame,or, if desired, these parts may be reversed. Attached to member A is thelower plate C of a hasp having hinged thereto an upper plate D. Se curedto plate D or formed integral therewith is a casing E, which containslocking mechanism adapted to coact with a staple F upon member B. PlateD may be secured to a hasp, if desired.

lap one another.

member A by means of cyebolt Cr, as shown in Fig. 1, if desired.

The preferred form of locking mechanism within the casing E is shown inFig. 4, and it is to be understood that this mechanism may be used inother relations without the use of Bolts l 1 are adapted to travel inparallel paths, guided by straps 2- 2, and in normal position the endsthereof over- 'I`he advantage of this overlapping feature in decreasingthe possibility of the picking of the lock will be obvious. Immediatelybelow the inner ends of these bolts when in normal or operativeposition, as shown in Fig. e, with the adjacent ends overlapping, is anopening' 3 in the lower plate 4 of casing E. This opening is adapted toadmit staple F or other enacting locking means in such position as toadapt it to be engaged by bolts 1. rlhe lower corners of bolts l arebeveled, as shown at l, in order to render the above action more easy.The

outer ends of bolts l are provided with pins 5, each pin being adaptedto pass through a slot 6 in levers 7. These levers are crossed and atthe point of intersection are pivotally mounted upon post 8, projectingfrom plate 4. Connecting' the arms of levers 7, which engage pins 5, isa spring 9, tending' to draw the same together, and thus hold bolts l 1in their innermost position, as shown in Fig. 5. rI he free arms oflevers 7 are adapted to be engaged and moved by the bits of a key, whichmay be inserted in a keyhole 10. (Shown in Fig'. 2.) Obviouslyapluralityof levers could be used in place of those shown, and thus require akey-bit peculiarly adapted to lit the same in order to withdraw thebolts, or other devices could be used to limit the requisite shape ofthe key; but these constructions are not shown, as they form no part ofthe present invention. Projecting from the bolt-cir gaging arms oflevers 7 are pins 11, adapted to be engaged and held apart by slide 12.This slide is secured to top plate 13 of casing E by means of slots 14and headed pins 15 and is provided with a post 16, adapted to projectthrough slot 17 in the same. By means of this post slide 12 maybereciprocated upon of spring 9. Vhen the upper portion of the the undersurface of plate 13 into and out of i the path of travel of pins 11.

The operation of this embodiment of my 'i invention is as follows: Withthe parts in norl mal position, let it be assumed that it is desired lto lock staple F within casing E. Opening 3 is placed over staple F andwith the beveled l surfaces of bolts 1 1 in engagement therewith. Thecasing is then pressed against the staple, and the beveled surfaces ofthe bolts 1 cause the same to be retracted against the tendency staplehas passed the bolts, spring 9 forces them inwardly through the openingin the same, as indicated in Fig. 4. It will be vnoted that in thisposition the staple and surrounding portion of member B are covered andprotected by the casing of the lock. Vhen it is desired to release thestaple, it is necessary to insert the proper key in keyhole 10 and turnthe same until the bits thereof engage levers 7 and move the same totheir outermost positions. This movement retracts 'bolts 1 and permitsthe withdrawal of the staple. If it is desired to maintain the device inan inoperative position-as, for example, to prevent accidental lockingthereof-the levers are retracted by means of a key, and slide 12 isinserted between pins 11. The locking mechanism is thus renderedinoperative until the slide is withdrawn, as levers 7 are held apart bythe same.

`In the embodiment of my invention shown in Figs. 1 and 6 bolts 18 arein alinement and abut against instead of overlapping one another. Thelower surfaces of the bolts are beveled, as shown at 18, insubstantially the same manner and for the same purpose as bolts 1 arebeveled at 1L in the previously-described embodiment. Bolts 18 havesockets 19 at their outer ends, and fitted within and adapted toreciprocate within the same are posts 20, projecting from the side wallsof casing E'. Spiral springs 21 encircle posts 2() and abutting againstbolts 18 and the side walls of casing E tend to keep the former in theirinnermost position. Rigidly secured to the tops of bolts 18 are arms 22,connected by toggle-links 28 and 24, the pin 25, pivotally connectingthe toggle-links, being adapted to reciprocate in a guide 26. Link 24extends beyond pin 25 in a position adjacent keyhole 10', Fig. 1, andforms a cam-surface adapted to coact with the bit of a key insertedtherein. The remaining parts of this embodiment are substantially thesame as that previously described. The operation of this embodiment ofmy invention differs from that previously described in that bolts 18 areretracted bythe action of the toggle-links 23 and 24, which are in turnactuated by the bit of the key coacting with the cam-surface on link 24.

It will thus be seen that I have provided a strong, simple, and reliablelocking device, the I several part-s of which are few and easily duplilcated and may be assembled by unskilled labor. Although shown in theaccompanying dravvings as positioned upon a hasp, the value of the lockalone to perform the functions of an ordinary lock will be obvious. Itwill also be noted that when used in connection with a hasp, as shown inFig. 2 of the drawings, the screws securing the hasp are covered whenthe lock is in operative position, and it will be understood that anymeans whereby the case of the lock may be opened are also upon the sidetoward the member on which it is adapted to be secured.

As many changes could be made in the above construction and manyapparently widely different embodiments of my invention could be madewithout departing from the scope thereof, I intend that all mattercontained in the above description and shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense. I desire it also to be understood that the language used in thefollowing claims is intended to cover all of the generic and specificfeatures of the invention herein described and all statements of thescope of the invention, which, as a matter of language, might be said tofall therebetween.
